Antisemitic incidents have spiked across the U.S. in the year since the Oct. 7 Hamas terrorist attack in Israel — an “avalanche” of disturbing reports as assaults, death threats, Nazi salutes and more have been reported at local schools.

The Anti-Defamation League recorded around 10,000 antisemitic incidents since Oct. 7, marking the largest year-to-year increase since the group started recording such incidents in 1979.

The Anti-Defamation League has found that cases of antisemitism have surged in the wake of the Oct. 7 attack by Hamas against Israel last year.
